A Greenwich shipping logistics company has entered into a purchase agreement that would more than triple the size of its workforce and expand its presence in contract logistics.

With the $615 million purchase of New Breed Holding Co., Greenwich-based XPO Logistics will increase its staff to 9,900 at 219 facilities from 3,100 at 148 locations.

New Breed, which had revenue of $597 million for the 12 months ending June 30, specializes in services for omni-channel distribution, reverse logistics, transportation management, freight bill audit and payment, lean manufacturing support, aftermarket support and supply chain optimization.

Headquartered in High Point, N.C., New Breed selects its customers in industries with high-growth outsourcing opportunities for complex supply chain requirements. It processes more than 275,000 orders per day through 71 facilities.

"We're making a transformational move in acquiring New Breed -- one that gives us critical mass and elevates our service offering," Bradley Jacobs, XPO chairman and CEO, said in a statement.

"We'll be able to deliver integrated, end-to-end logistics solutions for any company, of any size, with any combination of transportation needs. New Breed is a jewel in the crown of contract logistics: a world-class provider entrusted with critical services by some of the most prestigious corporate names in America."

The announcement follows the acquisitions of 3PD, NLM and Pacer in the past 12 months, and the company has just completed the purchase of Atlantic Central Logistics, a non-asset based provider of last-mile logistics with 14 East Coast locations.

"We view New Breed as the Rolls Royce of contract logistics," Jacobs said. "It's the leading provider of highly engineered solutions for blue chip companies."

The company has obtained commitments from Credit Suisse, Morgan Stanley Senior Funding, Citigroup and Deutsche Bank for a total of up to $645 million in senior secured term loan facilities to fund the New Breed transaction and general corporate purposes, including potential future acquisitions.

In a separate statement, XPO reported its second-quarter net loss narrowed to $14.5 million, or 28 cents per share, compared with $18.1 million, or $1 per share, in the same period last year. Revenue soared to $581 million from $137 million.

Shares of XPO jumped 19 percent, or $4.93, to $30.96 in Wednesday trading.

XPO's three business segments -- freight brokerage, expedited transportation and freight forwarding -- utilize relationships with ground, rail, sea and air carriers to serve more than 14,000 customers in the manufacturing, industrial, retail, commercial, life sciences and government sectors.

Founded in 1968, New Breed will retain its employees, according to XPO, which said the acquisition will double XPO's information technology workforce to about 600.

"A key IT opportunity for us relates to New Breed's transportation management system," Jacobs said. "We're very familiar with it because we're already a customer."
